Nowhere is that more applicable than in handling errors. It??™s simple to throw a bunch
of red borders and text around when something goes wrong, but those who cannot identify
the difference between red and black will be lost. Color is a powerful tool, but the
Web requires a more explicit visual mechanism. Consider coupling the error with an icon
that grabs a person??™s attention with equal power??”octagonal stop signs, yield symbols, and
information graphics are recognized by users around the world.
In addition to color and iconography, typographic treatments also work well. Bolding the
label of the field in question using a
tag is a reliable means of bringing attention
to the error. There are no problems with color information getting lost, no images to load,
and visitors using screen readers and other alternative devices will recognize which text is
emphasized.
Functionality. The functionality of the error messages is equally important. First and most
important is to ensure that the error reporting actually works??”rigorously test every field
and option to check if every possible error is displayed correctly, and for the right reasons.
